Reports methods where a parameter appears to be always the same constant.<br>
<br>
Example:
<pre>
<code>static void printPoint(int x, int y) { // x is always 0
  System.out.println(x + ", " + y);
}

public static void main(String[] args) {
  printPoint(0, 1);
  printPoint(0, 2);
}
</code>
</pre>
Quick fix: inlines the constant value. This may simplify the method implementation.
